perpetual energy for on board rechargable batt

[Fret Wire]

Those links work fine. Thanks Zach!, I got engrossed in robots, and forgot I was a guitar player! :shock: Neat stuff!  Do they make a Hopps sniffing chip that will allow my robot to bring a Mic Lite to the soldering bench?

the loss of efficiency and destruction of the tone of the pickups are always involved in connecting the pickup's output to any device that attempts to extract useful electrical energy. http://www.robotroom.com/XSBoost.html

In a Les Paul there are 2 pickups. When playing one, the other could be used to recharge the batt. I guess...
This is interesting
